The OPT301M is an Opto-electronic Integrated Circuit, containing a photodiode and trans-impedance amplifier on a single dielectrically isolated chip. The trans-impedance amplifier consists of a precision FET input op amp and an on-chip metal film resistor. The 0.09 x 0.09" photodiode is operated at zero bias for excellent linearity and low dark current. The integrated combination of photodiode and trans-impedance amplifier on a single chip eliminates the problems commonly encountered in discrete designs such as leakage current errors, noise pick-up and gain peaking due to stray capacitance. The OPT301M operates over a wide supply range (±2.25 to ±18V) and supply current is only 400μA.
